TSC ENABLES THE INTEGRATION OF GROWING SHARE OF DISPERSED GENERATION INTO THE HEAVILY MESHED NETWORK IN CENTRAL EUROPE

摘要

A group of twelve TSOs in Central and Eastern Europe have set up the TSO Security Cooperation (TSC) with a permanent TSO Security Panel, new video based cooperation tools for Control Centres and a common IT platform for data exchange (CTDS) performing joint N-1 security assessments. TSC's main goal is to ensure the overall system security of a large supranational region of the European network. All participating TSOs have the same view of the grid of the whole TSC region. Depending on the nature and the location of identified problems, the involved TSO(s) are jointly proposing solutions. Proposed or requested remedial actions are based on technical and economic analysis. A coordinated decision can be made jointly amongst the TSOs during the day-by-day conference call in the evening (DOPT) where TSOs whose grid might be affected by a remedial action have the opportunity to discuss any unintended side effects and alternatives that may be considered in order to resolve the congestion. In June 2012, TSC TSOs have started an operational trial phase on Multilateral Remedial Actions (MRAs). Following discussions with representatives of the relevant National Regulatory Authorities (NRAs) of the TSC region, cost recovery for activation of selected types of MRAs was approved on a temporary basis. The MRA procedure shall help the operational planners to propose multilateral remedial actions to resolve security violations when all other available single or bilateral remedial actions are already exhausted. TSC operational planners may now order redispatch capacities from all TSC members and not only from neighbouring TSOs as is standard in other regions. Based on the experiences on MRAs during the Trial Phase, the successful implementation of MRA operational procedures shall be further optimized and an enduring solution for cost sharing shall be developed and implemented consequently. The experiences gained in the TSC region will provide significant input for the work of ACER and ENTSO-E to identify an appropriate regulatory framework for cross-border redispatch including cost-sharing arrangements. At the end of 2012, the TSC TSOs have decided to implement a new Central Service Providing Entity (CSPE) in order to increase the efficiency, quality, coordination and a faster realisation of new tasks and TSOs' common services. The decentralised approach of TSC will not be altered by the implementation of this new entity but undoubtedly supported by various supportive services. From experience, the results of security assessment have been heavily depending on the data quality of the input data. Therefore CSPE shall establish common quality assessment and supervision processes which shall be available 24/7. CSPE will also be responsible for proposing improvements regarding data quality, adaption of data models and exception handling. CSPE and TSO bodies, like the Security Panel of Expert, will work hand in hand when developing new processes, e.g. operational planning, MRAs, capacity calculation or crisis coordination. Further on, CSPE shall become a facilitator for knowledge sharing (operational planning) and training of operators (planning and real-time operation) for TSC TSOs and partners providing learning content, trainers and facilities. As preliminary measures for the envisaged additional coordination, three so-called Cooperation Areas were established within TSC developing implementation concepts for Common Medium and Long-term Outage Planning (CA I), a D-2 Common Grid Model (CA II) and a Joint Training and Certification Program (CA III). All TSC activities follow an open approach addressing TSC and general TSO issues at the same time. TSC is open for additional TSOs which are interested to cooperate in the process of implementing an efficient, effective and secure system operation. The paper outlines the recent experiences of the cooperation of the TSOs in the TSC. In addition to the technical aspects the economic and regulatory aspects
